Abstract

A policy application method for Machine Type Communication (MTC) and a Policy and Charging Enforcement Function (PCEF) are provided by the disclosure. The method comprises that in a course in which an MTC device attached to a PCEF establishes an Internet Protocol-Connectivity Access Network (IP-CAN) session, the PCEF locally obtains a group policy corresponding to a device group to which the MTC device belongs (S302); the group policy is applied in the IP-CAN session (S304). The technical solution of the disclosure reduces the time required by applying the MTC policy by the PCEF, saves network resources, and increases utilization of the network resources.

Description

FIELD OF THE INVENTION

[0001] The disclosure relates to the communication field and more particularly to a policy application method for Machine Type Communication (MTC), and a Policy and Charging Enforcement Function (PCEF).BACKGROUND OF THE INVENTION

[0002] A 3rd Generation Partnership Project (3GPP) wireless core network comprises a General Packet Radio Service (GPRS) network, an Evolved Packet System (EPS) network, and a Universal Mobile Telecommunications System (UMTS).

[0003] FIG. 1 shows a schematic diagram of an emergency call performed by a piece of MTC User Equipment (UE) to access an Internet Protocol (IP) Multimedia Subsystem (IMS) through System Architecture Evolution (SAE) and a UMTS. In FIG. 1, the solid lines represent signalings, and the dashed lines represent IP channels of the subscriber. When the access is performed through the UMTS, the UE can be also called a Mobile Station (MS).

[0004] As shown in FIG. 1, main network elements involved when the MTC UE accesses an MTC ...
